"We are heartbroken to announce the untimely death of our friend, Ralphie May," the comedian's rep said in a statement to ET. "Ralphie had been battling pneumonia and had cancelled a handful of dates over the last month in an effort to recover. Earlier this morning at a private residence in Las Vegas his body was discovered, cause of death is cardiac arrest. "

"Two days ago he won the Casino Comedian of the Year at the Global Gaming Expo and had performances throughout the remainder of 2017 as part of his residency at Harrah's Las Vegas," the rep added. "May is survived by his wife Lahna Turner and children April June May and August James May.

May's manager released a statement as well, saying, "As his manager and his friend, I will miss his laugh, his generosity to fellow comedians, his trademark orneriness, and his enormous love of life. He left us entirely too soon -- and we can only wonder where his comedy might have taken all of us. We send our love to his family, his fans, and all the comics who shared stages with him across the country."

"It's a big loss, one that will no doubt be felt for years to come," he added.
